The criteria for sound to travel is presence of particles, sound can't travel in vacuum, it can in air, it can travel even better in water (you can hear roar of whales for huge distances), for example it can travel even better in metal (when you put your ear on a train rail, you can hear train from huge distances.) or just in steam (sound travels better in fog than in clear air, because water in the air is making the air thicker.)

Sound can travel through a vacuum is it true or false?

False. Sound requires a medium, such as air, water, or a solid material, to travel through. In a vacuum where there is no medium, sound cannot travel.


Is it true that sound waves can travel through a vacuum?

No, sound waves cannot travel through a vacuum because they require a medium (such as air, water, or a solid material) to propagate. In the absence of a medium, there is nothing for the sound waves to travel through, so they cannot propagate.


Is it true that spund waves can travel only theough aor?

Sound waves can travel through various mediums such as air, water, and solids. The speed of sound varies depending on the medium, with it traveling fastest through solids, followed by liquids, and then gases like air.


does sound travels in all mediums, true or false?

True. Sound can travel through solids, liquids, and gases. The speed and manner in which sound travels may vary depending on the medium through which it is moving.


True or false your distance from a sound source affects how loud the sound seems?

True. The farther away you are from a sound source, the lower the perceived loudness of the sound. This is because sound waves lose intensity as they travel through air, resulting in a decrease in perceived volume.


What is true about sound in a vacuum?

Sound cannot travel through a vacuum, it needs a medium to travel through as its the vibration of particles that allows its energy to progress


Is it true that sound waves travel faster through air than through solids?

Through solids because the particles are closer than gas particles.


Sound energy cannot pass through empty space true or false?

sound waves can only travel through particles as particles vibrate. this is why solids let sound pass easiest as the vibrations are passed on the easiest. in a vacuum there is no sound because there are no particles


Name 1 thing sound can't travel through and why?

Sound cannot travel through vacuums. It needs a medium for its waves to process, meaning the molecules need to vibrate in order for sound to be heard. Space is a good example of a vacuum that sound cannot travel through. In the movie Alien, they tag line : "In space, no one can hear you scream," and that is true.


What is the following true of sound waves?

Sound waves are mechanical waves that require a medium to travel through, such as air, water, or solid materials. The speed of sound waves varies depending on the medium they travel through. Sound waves are longitudinal waves, which means they move in the same direction as the vibration of particles in the medium that carries the sound.


Is it true sound is created when objects vibrate?

Yes, sound is created when objects vibrate and transmit energy through the air as pressure waves. These waves travel to our ears and are interpreted by our brain as sound.


Why can't sounds travel in a vacuum?

because sound waves are vibrations, and in a vacuum, there is nothing for the sound to go through.
